Like other reviews, the box the receiver came in was in tatters. (I ordered two, both boxes were damaged). The receiver itself is not secure in the box so it just bounces around and tears through the cardboard. UPS left it at my garage door with the mounting arm just hanging out of the box. Not that it matters all that much. After all it will be subject to salt, road wear and debris. All the bolts and installation materials are bagged and securely taped to the receiver so etrailer must be aware of their packing limitations.
Installation was a breeze for my Audi A3. Took about an hour. I highly recommend watching etrailer’s installation video before attempting. The one deviation I made from their method was to grind a bit of the bolt face edge off (see picture) to fit through the frame access. They grind off the rust proofing which I rather not do as I live in a region with road salt. The few millimeters I removed won’t impact the bolt strength. That and this is only for a bike rack.
I have one more to install and this one will be a bit more difficult as I have to remove the bumper cowling to gain access to the mounting points. It shouldn’t be difficult just time-consuming.
One other note. I’ve been eyeing these for a while now and waited for the spring sale. Saved a lot of $$$ by waiting.

More Than Just a Hitch – Thank You

I
got this trailer hitch receiver for my 2018 Audi A3 to attach a cargo basket while starting my welding career. At the time, I didn’t even have a truck…just big dreams and limited options. The price was great, shipping was fast (even to the middle of nowhere), and installation was super easy.

What etrailer didn’t know is that this small purchase helped me chase my dream. It gave me mobility, hope, and one of my first tools of independence as an aspiring welder. I’ll always be grateful. Here’s to humble beginnings!

This is my fourth Curt Hitch install and this is the first one which caused some disappointment. It is great quality but either the car or the hitch had to be modified to install. The holes for the mount are off by 1/4 inch. This is difficult to tell until you get the bolt in and at that point you really can't widen the holes in the frame of the car. I had to file out the holes in the hitch which took quite a bit of time and energy. So, the install was much more painful than it should have been but the hitch is great quality as always. Also, filed down the bolts to get those into the necessary space. Seems like alternative bolts would be easy to source.

So far excellent hitch. Nice quality zinc plated and beefy hardware. My only gripe is i had to shave down some of the hardware to get it installed on my particular model car. 2015 audi a3 tdi. Otherwise fit is perfect and looks good!

Still a solid hitch. As with anything that’s being jolted around under heavy loads I do recommend rechecking the torque after a few uses to make sure everything stays tight. After the checking and having to torque down some more it’s been good.

2105 Audi A3 Sedan. Installed the Curt Trailer Hitch Receiver 1-1/4". Had to drill out the front hole closer to the front of the car in the frame with a 1 1/3" step drill bit $12 to get the bolt and flat washer through the front hole. Only got 2 fish wires in package, so may (recommend) need to buy 2 more for the 7/16" bolt. Fish wiring takes a bit to get used to and don't loose the bolt in the frame(. Make sure the fish wire is really tightly screwed onto the bolt. Also bought the Yakima RidgeBack 2 Bike Rack 1-1/4" Tilting from etailer and as the picture shows it fits and looks great in the hitch.

Audi Parts has a nice 1 1/4" hitch cover with the 4 rings.

Thanks etrailer

No problem with the hitch. I followed the online recommendation and received the correct hitch. Upon attempted install of the hitch, the mounting bolts could not be fished through the frame access holes. The bolt heads were too large. Upon calling customer service, I was informed that this occurs sometimes but offered no other recourse. Nowhere does it say on the website or in the installation instructions that there might need to be some drilling or reaming, as Joe B. and Don had to do per their reviews. Just the opposite, the website states no grinding or drilling. The website needs to update this to reflect the possibility of having to take the hitch to an installer if you're not comfortable with grinding and drilling. I don't have jacks nor do I want to buy a step drill bit to make the holes larger. The whole idea was to buy the hitch and mount it without extra work. Had I known this, I would have just taken the car somewhere and had it installed instead of losing time.

The hitch is perfect! Installation was pretty simple and who would’ve known there was a hitch for my Audi car. I thought I would never be able to carry my bikes as I wouldn’t put them on my roof or the trunk. Customer service was fabulous at helping answer all my questions. Cost was cheaper than a local camping trailer/hitch shop. Will definitely look to them again for my next purchase!

Audi A3

Hitch was a pain to install (would have been much easier with the car on a lift) but I knew going in it wouldn't be easy. The directions were good and I got it done. Hitch has worked perfectly for my wife's Audi A3 - we use it to attach a 1Up bike rack to it and it is rock solid. Worth a few hours of work to save several hundred bucks if I had it installed somewhere.

Overall - very satisfied. Over the last 10 years and 3 cars, this is my third hitch from etrailer and so far the easiest. The product was simple and easy to install. Spot on with the instructions and all the parts. Had to jimmy with getting the bolts in one side of the frame but no cutting or grinding required. Fit is very good - I'd like about 1/4 to 3/8 more rearward travel - but it does work with my old bike mount. Packaging was good - maybe a few less staples would still work. The Curt receive is built like a brick house with very clean welds and a nice finish.

2017 Audi A3

I needed a hitch to carry my bike rack for my Audi A3. The etrailer website made that easy. The site is easy to use, showed the two models that are made for my car, described the differences. I ordered it on line and got a confirmation of my order, then later the same day was informed it that already shipped. It arrived very well packaged.
While it says no drilling needed, I found the heads of the bolts would not quite fit through the access hole. I think due to undercoating of the car, so had to "ream" it out a bit. The products it great, looks great and performs perfect.



by:

Great hitch. Fits my 2015 S3.



by:

Of course it took me twice as long to install
As
I expected, but I was able to do it without help. I love my hitch, it is almost invisible when looking at the car, and works perfectly.

Fantastic service, great shipping! Haven’t used the actual hitch yet, but the company is great.

Excellent instructions on the install and a great fit very happy with the purchase

Simply said as Fantastic. Order received as promised. The install instruction videos were great.

Holes don't line up on Audi A3
A 30
minutes install turn into 1 1/2 hour!
Not what I would call precision craftsmanship.
If you have an Audi A3, do yourself a favor and buy something else.
3rd Curt I install and this one is a MAJOR TURN OFF!

We found that when we installed on a 2019 Audi A3 that once the hardware was fish wired into place that the holes were slightly off so we used a die grinder to enlarge the holes on the frame enough to install. You can see that at time stamp 3:49 in the video install below.

  • What Trailer Hitch Fits The 2017 Audi A3 E-Tron
    Hello Ryan. The Curt Class 1 Hitch will not fit the 2017 Audi A3 e-tron, because the manufacturer specifies it will not fit the e-tron model. The only hitch for the 2017 Audi A3 e-tron is the stealth hitch # SH46ZR. This comes complete with the hitch, towing kit and wiring harness.

  • Best Hitch and E-Bike Rack for 2018 Audi A3
    The hitch I suggest for your 2018 Audi A3 is the Curt # C11399. I recommend this Class I hitch because it easily bolts on with included hardware (no drilling except you will need to enlarge some existing holes) and because its main cross tube will be mostly hidden behind your rear bumper fascia for a clean look. Installation instructions are linked for you. Since you have fairly heavy e-bikes you'll need a special bike rack made for that extra weight. The rack that I recommend is the industry-leading...

    For your 2016 Audi A3 the correct part number for the Curt hitch is part # C11399. Curt recommends using the Curt Trailer Hitch Support Strap part # 18050 to reduce chucking and jarring for all non-towing applications. The support strap must be used to abide by their warranty. The Curt hitch is made in the U.S.A. This is a great option for you.

  • Availability Of Trailer Hitch For 2024 Audi A3 Quatro
    Hello Paul, thanks for reaching out. The Curt # C11399 is not listed for the 2025 Audi A3, because according to the manufacturer, it is only confirmed to fit the 2015-2020 A3. It has not been tested on or confirmed for the 2025 model since we always stick to the manufacturers fitment guide. Sadly, there is no hitch for the 2025 Audi A3 Quatro, so if you need to carry cargo, the only option would be to do so with a roof rack like the Thule # TH25AG along with a roof mounted cargo carrier...

  • Towing a Jet Ski Trailer with a 2015 Audi a3
    Yes you are correct that we only carry Class I hitches for this vehicle because Class II hitches are generally too heavy duty for towing with vehicles like your 2015 Audi A3. One point to check first would be the weight of the jet ski and trailer. A jet ski could weigh between 450-1100lbs and a trailer an additional 250lbs or more. I looked up the maximum trailer weight in the owners manual that let me know a trailer for your vehicle is limited to a typical Class 1 or Class 2 trailer....

  • Is Lift Needed to Install Curt Hitch on 2017 Audi A3 or Drop Exhaust or Bumper Fascia
    I checked with Curt and to install the hitch part # C11399 on a vehicle like your 2017 Audi A3 it is not required that you jack up the rear of the vehicle. There's enough clearance at the rear of the vehicle. Nothing gets removed from the vehicle to install the hitch either like the rear bumper or exhaust. Thankfully the hitch just raises into position without interference. The only think you will have to do is enlarge some existing holes by drilling, filing, or using a rotary tool.

This is a wheel mount bike rack with a weight capacity of 60 lbs per bike so if your bikes don't have front fenders and you remove the battery on each (which I'm assuming the 125 lbs is with the batteries) this will work great!
